question

Consider the formation ofethylcyclohexane(C_8H_16) C_8H_10(l) + 3H_2(g) = C_8H_16\DeltaH298°K= - 48.3 kcal and C_8H_8(l) + 4H_2 (g) = C_8H_16\DeltaH_298°K = - 74.65 kcal . Given that at 298°K, the heats of combustion of C_8H_16 to water vapor and CO_2 is - 1238.23 kcal/mole, and the heats of formation of water vapor and CO_2 are, - 58.32 and - 94.05 kcal/mole respectively, calculate (a) heat of hydrogena-tion of styrene toethylbenzene. (b) the heat of formation ofethylbenzene.
